No. I'm just using the standard config

If you're implying I should?

The problems I've come across have become evident with as little work as
this:
- run "initdb"
- start postgres
- run "psql" to import the dumped data
- run for a short period of time (less than an hour)
- shutdown postgres
- reboot
- postgres starts
- the large tables are now missing

With the above, I wouldn't have thought there is enough time to do
vacuums,
which seem to take quite a while on large tables. The activity is a
mixture
of inserts and updates (from triggers and plsql functions.)
